agricultural chemicals.
Netherlands Patent No. 121,788, published Sept. 15, 1966, teaches
the preparation of compounds of Formula (i), and their use as
general or selective herbicides, ##STR1## WHEREIN R.sub.1 and
R.sub.2 may independently be alkyl of 1-4 carbon atoms; and
R.sub.3 and R.sub.4 may independently be hydrogen, chlorine or
alkyl of 1-4 carbon atoms.
Compounds of Formula (ii), and their use as antidiabetic agents,
are reported in J. Drug Res. 6, 123 (1974) ##STR2## WHEREIN R is
pyridyl.
The presence of undesired vegetation causes substantial damage to
useful crops, especially agricultural products that satisfy man's
basic food needs, such as soybeans, corn, wheat, and the like. The
current population explosion and concomitant world food shortage
demand improvements in the efficiency of producing these crops.
Preventing or minimizing the loss of a portion of such valuable
crops by killing, or inhibiting the growth of undesired vegetation
is one way of improving this efficiency.
A wide variety of materials useful for killing, or inhibiting
(controlling) the growth of undesired vegetation is available; such
materials are commonly referred to as herbicides. However, the need
exists for still more effective herbicides that destroy or retard
weeds without causing significant damage to useful crops. Some
weeds (nutsedge is a particular example) are very difficult to
control; many of the herbicides that are used to control nutsedge
are so nonselective that they cause damage to the crops
themselves.

Synthesis
As shown in Equation 1, the compounds of Formula I can be prepared
by combining an appropriate 2-amino-1,3,5-triazine of Formula III
with an appropriately substituted sulfonyl isocyanate or
isothiocyanate of Formula II; R.sub.1, W, X and Z being as
previously defined. ##STR9##
The reaction is best carried out in inert aprotic organic solvents
such as methylene chloride, tetrahydrofuran or acetonitrile, at
ambient pressure and temperature. The mode of addition is not
critical; however, it is often convenient to add the sulfonyl
isocyanate or isothiocyanate to a stirred suspension of the
aminotriazine. Since such isocyanates and isothiocyanates usually
are liquids, their addition is more easily controlled.
The reaction is generally exothermic. In some cases, the desired
product is insoluble in the warm reaction medium and crystallizes
from it in pure form. Products soluble in the reaction medium are
isolated by evaporation of the solvent, trituration of the solid
residue with solvents such as 1-chlorobutane, ethyl ether, or
pentane, and filtration.
In certain cases, it may be possible to obtain isomeric products
from the reaction shown in Equation 1. Such isomeric products would
result from addition of compound II to an endocyclic nitrogen atom
of aminotriazine III and have the structure exemplified below:
##STR10##
It is to be understood that the products resulting from the
addition of a compound of Formula II to the exocyclic as well as
the endocyclic nitrogen atoms of triazine III are to be considered
a part of this invention.
The intermediate sulfonyl isocyanates of Formula II (wherein W is
O) can be prepared by reacting corresponding sulfonamides with
phosgene in the presence of n-butyl isocyanate are reflux in a
solvent such as chlorobenzene, according to the procedure of H.
Ulrich and A. A. Y. Sayigh, Newer Methods of Preparative Organic
Chemistry, Vol. VI p 223-241, Academic Press, New York and London,
W. Foerst Ed. In cases where formation of the desired sulfonyl
isocyanate is difficult by the above procedure the sulfonyl urea
formed by reaction of butyl isocyanate with the appropriate
sulfonamide is treated with phosgene according to the above
reference.
The preparation of sulfonamides from ammonium hydroxide and
sulfonyl chlorides is widely reported in the literature, e.g.
Crossley et al., J. Am. Chem. Soc. 60, 2223 (1938). See also J.
Org. Chem. 18, 894 (1953) for the preparation of
2-furansulfonamide.
Certain sulfonyl chlorides are best prepared by chlorosulfonation
of a substituted benzene, naphthalene, or thiophene according to
the teaching of H. T. Clarke et al. Org. Synth. Coll. Vol. 1, 2nd
Ed. 1941, p. 85. Other benzenesulfonyl chlorides are best made by
diazotization of the appropriate aniline with sodium nitrate in
HCl, followed by reaction of the diazonium salt with sulfur dioxide
and cuprous chloride in acetic acid according to the teaching of H.
L. Yale and F. Sowinski, J. Org. Chem. 25 1824 (1960).
Furansulfonyl chlorides are best prepared as shown in Equation 2.
##STR11##
Sulfonyl isothiocyanates can be prepared by treatment of
sulfonamides with carbon disulfide and potassium hydroxide followed
by reaction of the dipotassium salt with phosgene according to the
teaching of K. Hartke, Arch. Pharm., 299, 174 (1966).
2-Amino-1,3,5-triazines can be synthesized according to methods
described by E. M. Smolin and L. Rapoport, supra, and by K. R.
Huffman and F. C. Shaefer, U.S. Pat. No. 3,154,547.
Agriculturally suitable salts of compounds of Formula I are also
useful herbicides and can be prepared by a number of ways known to
the art. For example, metal salts can be made by treating compounds
of Formula I with a solution of an alkali or alkaline earth metal
salt having a sufficiently basic anion (e.g. hydroxide, alkoxide,
carbonate or hydride). Quaternary amine salts can be made by
similar techniques.
Salts of compounds of Formula I can also be prepared by exchange of
one cation for another. Cationic exchange can be effected by direct
treatment of an aqueous solution of a salt of a compound of Formula
I (e.g., alkali metal or quaternary amine salt) with a solution
containing the cation to be exchanged. This method is most
effective when the desired salt containing the exchanged cation is
insoluble in water and can be separated by filtration.
Exchange may also be effected by passing an aqueous solution of a
salt of a compound of Formula I (e.g. an alkali metal or quaternary
amine salt) through a column packed with a cation exchange resin
containing the cation to be exchanged. In this method, the cation
of the resin is exchanged for that of the original salt and the
desired product is eluted from the column. This method is
particularly useful when the desired salt is water-soluble.
Acid addition salts, useful in this invention, can be obtained by
reacting a compound of Formula I with a suitable acid, e.g.
p-toluenesulfonic acid, trichloroacetic acid or the like.
The compounds of this invention and their preparation are further
illustrated by the following examples wherein temperatures are
given in degrees centigrade.
EXAMPLE 1
N-[(4,6-Dimethyl-1,3,5-triazin-2-yl)aminocarbonyl]-2-methylbenzenesulfonami
de
To 12.3 g 2-amino-4,6-dimethyl-1,3,5-triazine in 250 ml of dry
acetonitrile was added, with stirring, 19.7 g of
2-methylbenzenesulfonyl isocyanate at a rate designed to avoid
excessive heating of the reaction mixture. Stirring was continued
until the desired product crystallized. The product was removed by
filtration, washed with a small amount of ethyl ether and dried.
The resulting product,
N-[(4,6-dimethyl-1,3,5-triazin-2-yl)aminocarbonyl]-2-methylbenzenesulfonam
ide, melted at 141.degree.-145.degree. C.
EXAMPLE 2
N-[(4,6-Dimethyl-1,3,5-triazin-2-yl)aminocarbonyl]-2-chlorobenzenesulfonami
de
To 12.3 g of 2-amino-4,6-dimethyl-1,3,5-triazine in 200 ml of
acetonitrile was added with stirring 21.7 g of
2-chlorobenzenesulfonyl isocyanate. All of the solid dissolved
after the reagents were added and the mixture was then evaporated
to dryness. The solid residue was triturated with ethyl ether and
isolated by filtration to give impure
N-[(4,6-dimethyl-1,3,5-triazin-2-yl)aminocarbonyl]-2-chlorobenzenesulfonam
ide melting at 115.degree.-118.degree. C. The nuclear magnetic
resonance absorption spectrum of this product, in trifluoroacetic
acid, showed singlet peaks at 2.69 and 2.9 parts per million.
EXAMPLE 3
N-[(4,6-dimethoxy-1,3,5-triazin-2-yl)aminocarbonyl]-2-chlorobenzenesulfonam
ide
To 15.6 g of 2-amino-4,6-dimethoxy-1,3,5-triazine in 300 ml of dry
methylene chloride containing 0.1 g 1,4-diazabicyclo[2,2,2]octane
was added 21 g 2-chlorobenzenesulfonyl isocyanate with stirring.
The mixture was stirred for 16 hours and the resultant solid was
removed by filtration. After washing the solid with 1-chlorobutane,
the resulting product,
N-[(4,6-dimethoxy-1,3,5-triazin-2-yl)-aminocarbonyl]-2-chlorobenzenesulfon
amide melted at 188.degree.-189.degree. C. Infrared absorption
analysis showed absorption peaks at 1740 cm.sup.-1, 1630 cm.sup.-1
and 1595 cm.sup.-1 which are typical for this type of compound.
By using the procedure of Examples 1-3 with an equivalent amount of
the appropriate aminotriazine and the appropriately substituted
sulfonyl isocyanate, the compounds given in Table I can be

Formulations
Useful formulations of the compounds of Formula I can be prepared
in conventional ways. They include dusts, granules, pellets,
solutions, suspensions, emulsions, wettable powders, emulsifiable
concentrates and the like. Many of these may be applied directly.
Sprayable formulations can be extended in suitable media and used
at spray volumes of from a few liters to several hundred liters per
hectare. High strength compositions are primarily used as
intermediates for further formulation. The formulations, broadly,
contain about 0.1% to 99% by weight of active ingredient(s) and at
least one of a) about 0.1% to 20% surfactants(s) and b) about 1% to
99.9% solid or liquid diluent(s). More specifically, they will
contain these ingredients in the following approximate
proportions:
TABLE V
__________________________________________________________________________
Active Ingredient Diluent(s) Surfactant(s)
__________________________________________________________________________
Wettable Powders 20-90 0-74 1-10 Oil Suspensions, Emulsions,
Solutions 3-50 40-95 0-15 (including Emulsifiable Concentrates)
Aqueous Suspensions 10-50 40-84 1-20 Dusts 1-25 70-99 0-5 Granules
and Pellets 0.1-95 5-99.9 0-15 High Strength Compositions 90-99
0-10 0-2
__________________________________________________________________________
Lower or higher levels of active ingredient can, of course, be
present depending on the intended use and the physical properties
of the compound. Higher ratios of surfactant to active ingredient
are sometimes desirable, and are achieved by incorporation into the
formulation or by tank mixing.
Typical solid diluents are described in Watkins, et al., "Handbook
of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books,
Caldwell, N.J. The more absorptive diluents are preferred for
wettable powders and the denser ones for dusts. Typical liquid
diluents and solvents are described in Marsden, "Solvents Guide",
2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is
preferred for suspension concentrates; solution concentrates are
preferably stable against phase separation at 0.degree. C.
"McCutcheon's Detergents and Emulsifiers Annual", MC Publishing
Corp., Ridgewood, N.J., as well as Sisely and Wood, "Encyclopedia
of Surface Active Agents", Chemical Publishing Co., Inc., New York,
1964, list surfactants and recommended uses. All formulations can
contain minor amounts of additives to reduce foam, caking,
corrosion, microbiological growth, etc.
The methods of making such compositions are well know. Solutions
are prepared by simply mixing the ingredients. Fine solid
compositions are made by blending and, usually, grinding as in a
hammer or fluid energy mill. Suspensions are prepared by wet
milling (see, for example, Littler, U.S. Pat. No. 3,060,084).
Granules and pellets may be made for spraying the active material
upon preformed granular carriers or by agglomeration techniques.
See J. E. Browning, "Agglomeration", Chemical Engineering, Dec. 4,
1967, pp. 147ff. and "Perry's Chemical Engineer's Handbook", 4th
Ed., McGraw-Hill, New York, 1963, pp. 8-59 ff.

The compounds of Formula I can be formulated using the procedures
of Examples 7-21.
UTILITY
The compounds of Formula I are useful as herbicides. They may be
applied either pre- or postemergence for the control of undesired
vegetation in noncrop areas or for selective weed control in
certain crops, e.g., wheat. Some of these compounds are useful for
the pre- and/or postemergence control of nutsedge. By properly
selecting rate and time of application, compounds of this invention
may be used to modify plant growth beneficially.
The precise amount of the compound of Formula I to be used in any
given situation will vary according to the particular end result
desired, the use involved, the weeds to be controlled, the soil
type, the formulation and mode of application, weather conditions,
etc. Since so many variables play a role, it is not possible to
state a rate of application suitable for all situations. Broadly
speaking, the compounds of this invention are used at levels of
about 0.005 to 20 kg/ha with a preferred range of 0.01 to 10 kg/ha.
The lower rates of the range will generally be selected for lighter
soils, for selective weed control in crops, or in situations where
maximum persistence is not necessary. Some of the compounds of
Formula I can be used at very low rates for plant growth
modification, but higher rates may also be useful, depending on
factors such as the crop being treated, timing of treatment,
etc.
The compounds of Formula I may be combined with other herbicides
and are particularly useful in combination with
3-(3,4-dichlorophenyl)-1,1-dimethylurea, the triazines such as
2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine, the uracils
such as 5-bromo-3-sec-butyl-6-methyluracil,
N-(phosponomethyl)glycine,
3-cyclohexyl-1-methyl-6-dimethylamino-s-triazine-2,4(1H,3H)-dione,
N,N-dimethyl-2,2-diphenylacetamide, 2,4-dichlorophenoxyacetic acid
(and closely related compounds),
4-chloro-2-butynyl-3-chlorophenylcarbamate (Carbyne.RTM.),
diisopropylthiolcarbamic acid, ester with 2,3-dichloroallyl alcohol
(Avadex.RTM.), diisopropylthiolcarbamic acid,
S-(2,3,3-trichloroallyl) ester (Avadex.RTM.BW),
ethyl-N-benzoyl-N-(3,4-dichlorophenyl)-2-aminopropionate
(Suffix.RTM.), 1,2-dimethyl-3,5-diphenylpyrazolium methyl-sulfate
(Avenge.RTM.),
methyl(2-[4-(2,4-dichlorophenoxy)-phenoxy]-propanoate
(Hoelon.RTM.),
4-amino-6-tert-butyl-3-(methylthio)-1,2,4-triazin-5(4H)-one
(Lexone.RTM.), 3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea
(Lorox.RTM.), 3-isopropyl-1H-2,1,3-benzothiodiazin-(4)-3H-one
2,2-dioxide,
.alpha.,.alpha.,.alpha.-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine,
1,1'-dimethyl-4,4'-bipyridinium ion, monosodium methanearsonate,
2-chloro-2',6'-diethyl-(methoxymethyl) acetanilide, and
1,1-dimethyl-3-(.alpha.,.alpha.,.alpha.-trifluoro-m-tolyl)urea
(Cotoran.RTM.).
The activity of these compounds was discovered in greenhouse tests.
The tests are described and the data resulting from them are shown
below.
TEST PROCEDURE
Seeds of crabgrass (Digitaria sp.), barnyard-grass (Echinochloa
crusgalli), wild oats (Avena fatua), Cassia tora, morningglory
(Impomoea sp.), cocklebur (Xanthium sp.), sorghum, corn, soybean,
rice, wheat and nutsedge tubers were planted in a growth medium and
treated preemergence with the chemicals dissolved in a
nonphytotoxic solvent. At the same time, cotton having five leaves
(including cotyledonary ones), bush beans with the third
trifoliolate leaf expanding, crabgrass with two leaves,
barnyardgrass with two leaves, wild oats with one leaf, cassia with
three leaves (including cotyledonary ones), morningglory with four
leaves (including the cotyledonary ones), cocklebur with four
leaves (including the cotyledonary ones), sorghum with three
leaves, corn with three leaves, soybean with two cotyledonary
leaves, rice with two leaves, wheat with one leaf, and nutsedge
with three-five leaves were sprayed. Treated plants and controls
were maintained in a greenhouse for 16 days, then all species were
compared to controls and visually rated for response to
treatment.

Utility of the compounds of the invention for selective weed
control in wheat was first observed in a number of greenhouse
tests. The four tests described below (A, B, C and D) illustrate
that utility.
TEST A
Two 25 cm - diameter plastic bulb pans were filled with fertilized
and limed Fallsington silt loam soil. One pan was planted with
corn, sorghum and several grassy weeds. The other pan was planted
with soybeans, purple nutsedge (Cyperus rotundus), and several
broadleaf weeds. The following grassy and broadleaf species were
planted: carbgrass (Digitaria sanguinalis), barnyardgrass
(Echinochloa crusgalli), wild oats (Avena fatua), johnsongrass
(Sorghum halepense), giant foxtail (Setaria faberii), Kentucky
bluegrass (Poa pratensis), cheatgrass (Bromus secalinus), mustard
(Brassica arvensis), cocklebur (Xanthium pennsylvanicum), pigweed
(Amaranthus retroflexus), curly indigo (Aeschynomene virginica),
morningglory (Ipomoea hederacea), Cassia (Cassia tora), teaweed
(Sida spinosa), velvetleaf (Abutilon theophrasti), and jimsonweed
(Datura stramonium). In addition, two 12.5 cm - diameter paper cups
were filled with prepared soil; one was planted with rice and
wheat, the other with sugarbeets. The above four containers were
treated preemergence, i.e., the compounds were sprayed on the soil
surface before seed germination.
Twenty-eight days after treatment, the plants were evaluated. The
data obtained are summarized in Table VII. It should be noted that
wheat has more tolerance for the compounds tested than most weed
species.

TEST B
Twenty-five cm - diameter plastic pots filled with Fallsington silt
loam were planted with soybean, cotton, alfalfa, corn, rice, wheat,
sorghum, velvetleaf (Abutilon theophrasti), sesbania (Sesbania
exaltata), Cassia (Cassia tora), morningglory (Ipomoea sp.),
jimsonweed (Datura stramonium), cocklebur (Xanthium
pennsylvanicum), crabgrass (Digitaria sp.), nutsedge (Cyperus
rotundus), barnyardgrass (Echinochloa crusgalli), giant foxtail
(Setaria faberii) and wild oats (Avena fatua). Approximately 21/2
weeks after planting, the young plants and the soil around them
were sprayed overall with the test chemicals dissolved in a
nonphytotoxic solvent. Fourteen days after treatment, all species
were compared to untreated controls and visually rated for response
to treatment. The data are presented in Table VIII.

The following test illustrates the utility of these compounds for
the control of nutsedge.
Nutsedge (Cyperus rotundus) tubers (5 per pot) were planted
approximately 2.5 cm deep in 10 cm pots containing Fallsington silt
loam soil. Each compound to be evaluated was applied as a
preemergence soil surface spray, a directed tuber spray, soil
incorporated throughout the top 2.5 cm of soil and sprayed
postemergence on the foilage of plants approximately 8-10 cm tall.
The compounds were dissolved in a suitable solvent and applied at a
spray volume of 560 l/ha. The effects of chemical treatment on
plant growth were visually evaluated four weeks after treatment.
The results of these tests are given in Table XII.

PLANT GROWTH REGULANT USES
In addition to their use as herbicides, compounds of Formula I are
useful as agents to beneficially modify growth of selected plant
species. Rates (usually 0.01 to 1.0 kg/ha) and timing of
application are selected according to species to achieve desirable
effects with a minimum of phytotoxicity. Both vegetative and
reproductive growth may be controlled. Examples below illustrate
the response of sugarcane and sorghum to compounds of this
invention. In sugarcane and sorghum, a "chemical ripening" effect
is produced which results in a greater yield of soluble solids
(mostly sugars). In many other grasses, growth and seed stalk
development are restricted by these compounds which reduces mowing
requirements. These compounds also are useful for growth control of
woody and herbaceous broadleaf plants.
EXAMPLE A
Dwarf sugarcane plants, 6-8 months old, grown 3-5 stalks (1.5-3
meters tall) per 25 cm pot were sprayed with the compounds given
below (2 pots per compound). Each stalk was measured to the highest
visible leaf collar at the start and end of the study to determine
effects on growth in height. When stalks were harvested, 5 weeks
after treatment, juice was extracted therefrom and soluble solids
determined at the centers of the top, middle and bottom thirds of
each stalk. In stalks treated with compounds of this invention,
soluble solids were increased and growth was restricted as compared
to the solvent control (500 l/ha water plus surfactant Tween
20.RTM. at 0.2%). Results of this test are shown in Table XIII.

EXAMPLE B
Tracy sweet sorghum plants grown one per 15 cm pot to a stage just
prior to head emergence were sprayed with compounds given below.
Visual effects were noted about 3 weeks after spraying, then at 4
weeks plants were harvested and soluble solids determined at the
centers of the top, middle, and bottom thirds of each stalk.
Percent soluble solids was increased and growth and flowering were
restricted. Data from this test are shown in Table XIV.
